On the development of a system of palletizers for washing of saline and salty soil in Uzbekistan
Abstract
The analysis of the work of farms, cultivated crops on irrigated lands confirmed by salinity, showed the impossibility of obtaining high yields on these lands without removing the excess of water-soluble salts from the root layer of the soil, which is achieved by washing against the background of drainage. The main method of flushing saline lands is flushing by flooding checks without passing water from check to check, and for this purpose, farms make pal (earthen rollers) palletizers. The analysis and experience of their use showed that the height (main parameter) of the pallet-"h" produced by the above-mentioned palletizers does not correspond to the modern requirements of agricultural technology, agromelioration and ecology, which leads to a decrease in yield and product quality. The author proposed a mathematical model for establishing the rational height of the log (check) "h", taking into account the total washing rate (Q), mechanical composition, physical, chemical and mechanical properties of the soil and the number of salt washing (multiplicity) of water supply (Z), etc. The use of a palletiser system for washing for lands with different conditions of salinity and saline soils, the parameters of which, selected according to the proposed model, provide an increase in productivity and a decrease in the cost of production of agricultural crops cultivated on these soils.
